Title: Microprogram control storage
Inventor: KAWAGISHI TAIJI
IPC: G06F11/10
Filed: 1990-03-20
Abstract: PURPOSE:To minimize a decrease in performance due to error correction by comparing one-bit error with a past syndrome if the error occurs and controlling an error correction write mode when the error matches the syndrome. CONSTITUTION:When an error detecting circuit 5 detects the one-bit error, a bit inverting circuit 2 sets corrected data in a microprogram read register 4 and the data is set in the control storage again. If the one-bit error occurs frequently in this case, it is judged that the one-bit error is an error which can not be corrected and written; if the counted value of a counter 10 reaches a constant value, a mode FF 11 is inverted to enter a write inhibition mode and when the one-bit error is detected, microinstructions are executed immediately right after the error correction without writing it in the microprogram control storage 1. Consequently, even when the correction by rewriting is ineffective, writing operation is inhibited to minimize the decrease in the performance due to the error correction.

Title: Optical device using semiconductor laser
Inventor: MORISHITA ICHIRO
IPC: G02B27/00
Filed: 1989-03-23
Abstract: PURPOSE:To easily compensate astigmatic difference by arranging a lens, which irradiates a beam shaping surface with laser luminous flux in a divergent luminous flux state between a semiconductor laser and the beam shaping surface. CONSTITUTION:The lens 11 is interposed between the semiconductor laser 1 and an anamorphic prism 13 and the laser luminous flux emitted from a light emission point 0 is diverged slightly by this lens 11 and made incident on the beam shaping surface. When the diverged luminous flux is made incident on the beam shaping surface which is arranged slantingly, the astigmatism is generated because of the asymmetry of the angle of incidence. When the laser luminous flux is made incident on the slanting surface and expanded in luminous flux diameter in the direction where the sectional diameter is small, this direction is the one wherein the astigmatism cancels the astigmatic difference of the semiconductor laser. Consequently, the astigmatic difference of the semiconductor laser is easily compensated.

Title: Transmission line switching system
Inventor: OZAKI HIROICHI
IPC: H04B1/74
Filed: 1990-03-22
Abstract: PURPOSE:To prevent frame synchronizing step-out or undesired issuing of alarm at an opposite station reception side even when connection change is implemented by employing an elastic buffer memory for a standby transmission line signal transmission section so as to supply a readout clock independently. CONSTITUTION:A proper phase difference is given to frame pulses 12a, 12b and 12c in a device applied to low speed side signal processing branching sections 1, 2, 3 by using delay circuits 13a, 13b and the length of a path through which input signals S1, S2, S3 reach a standby system high speed signal processing transmission section 14 via connection switches 4, 5, 6 is made identical to the signals. Since the path from the low speed side signal processing branching section 3 till the standby system high speed signal processing transmission section 14 is longest, no delay is provided to the frame pulse 12c. Thus, even when any of the low speed side input signals S1, S2 and S3 is given to the standby transmission line, the phase of the frame of the signal inputted to the standby system high speed signal processing transmission section 14 is made equal to each other.

Title: Player capable of automatic music selection
Inventor: MORITA YUTAKA
IPC: G11B19/12
Filed: 1982-04-30
Abstract: PURPOSE:To attain the accurate automatic music selection, by using both detection information of non-sound state and position information of a intermusic band stored in advance, and controlling the muting at the intermusic band. CONSTITUTION:In a non-sound state detection circuit NSD, the AC component only is fed to a peak value hold circuit PH. The circuit PH has a required time constant and when the input is lost, an output voltage of the circuit PH is decreased. Since a comparator 12 outputs a detection signal when a voltage from the PH is lower than a reference voltage from a control circuit CTC, the detection signal is outputted when the signal is a non-sound state for a prescribed time. The control circuit CCT supplies an operation release signal to a muting circuit 6 based on it, applies the operation release signal and outputs a reproducing signal. In case of a live disc, the intermusic band is detected by providing a control signal turning off the muting from the controller CCT to the circuit 6 by the intermusic position information stored in advance as to the intermusic band just before the objective music.

Title: Isolation circuit
Inventor: KOIZUMI AKIO
IPC: H03F1/26
Filed: 1989-03-24
Abstract: PURPOSE:To improve the isolation characteristics by securing an equal impedance level when the front step side is viewed from the inverted and non-inverted input terminals of an amplifier respectively. CONSTITUTION:The audio signals of terminals T1 and T2 are supplied to an inverted input terminal and a non-inverted terminal of an amplifier 22 through amplifiers 21 and 24 respectively and furthermore to a speaker 24 through both amplifiers 22 and 23. The impedance levels R5 and R6 are equal to each other when the front step side is viewed from the inverted and non-inverted input terminals of the amplifier 22 respectively because the output impedances of amplifiers 21 and 24 are approximately equal to zero. Therefore the noises applied to lines 3A and 3B of a cable 3 are supplied to the amplifier 22 in the in-phase and at the same level and therefore offset to each other by the amplifier 22. Thus these noises are never supplied to the rear step. As a result, the isolation characteristics are improved.

IPC: G02F1/1339
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal alignment of liquid crystals around spacers and between the spacers by using polymer particulates which are colored and have a specific nonionic hydrophilic unit and fluorine in the polymer constituting their surface. SOLUTION: The nonionic hydrophilic unit expressed by the formula and the fluorine exist in the polymer constituting the surfaces of the polymer particulates. In the formula, R denotes an alkylene group. The polymer particulates may be synthesized by an ordinary suspension polymn. For example, a fluorine-contg. monomer, crosslinkable monomer and other monomers are copolymerized by using a water-soluble high-polymer dispersing material having the nonionic hydrophilic unit expressed by the formula in the presence of a polymn. initiator. The content of the nonionic hydrophilic unit expressed by the formula in the polymer constituting the surfaces of the polymer particulates is preferably 10 to 60 wt.%. If the content is below 10 wt.%, the adhesiveness and sprayability are degraded in some cases.  If the content exceeds 60 wt.%, the effect of preventing the abnormal alignment of spacers is lost in some cases.
